    gdb/testsuite: update gdb.tui/tui-nl-filtered-output.exp
    
    Following on from the previous commit, in this commit I am updating
    the test script gdb.tui/tui-nl-filtered-output.exp to take account of
    the changes in commit:
    
      commit 9162a27c5f5828240b53379d735679e2a69a9f41
      Date:   Tue Nov 13 11:59:03 2018 -0700
    
          Change gdb test suite's TERM setting
    
    In the above commit the TERM environment variable was changed to be
    'dumb' by default, which means that tests, that previously activated
    tui mode, no longer do unless TERM is set to 'ansi'.
    
    As the gdb.tui/tui-nl-filtered-output.exp script didn't do this, the
    test stopped working.  As the expect patterns in this script were
    pretty generic no tests actually started failing, and we never
    noticed.
    
    In this commit I update the test script to correctly activate our
    terminal emulator, the test continues to pass after this update, but
    now we are testing in tui mode.
